The best suggest I have is to give their technical support department a call, or post a message on their own support forum. You'll want to do things like have the exact version number of the software and its virus signature database file ready to give them, as well as the exact name of the file s being flagged, and, if you really want to be helpful, the SHA-1 hash or MD5 sum for each detected file.
That should be enough information to help their tech support folks start an investigation. Search In. McAfee blocks opening pdf files with Adobe Acrobat reader. Share More sharing options Followers 0.

On some occasions, however, you may find SmartScreen overstepping its bounds and blocking you from downloading a file you know to be safe.
I don't recommend turning SmartScreen off completely because it is helpful in preventing you from downloading a malicious file or app, but you can disable it in Microsoft's Edge browser if you want to override its protection and go ahead and download a file it doesn't recognize. You can disable SmartScreen in the Windows Defender Security Center app in total or just for Edge, but for the latter it's faster to do so right within Edge itself, particularly if you are already using Edge.
Here's how to toggle SmartScreen off and on in Edge:. Show only Search instead for. Did you mean:.
